HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 999, 3399, 1285 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 999, 3399, 1285 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 999, 3399, 1285 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 999, 3399, 1285 is 1.
HCF(999, 3399, 1285) = 1
HCF of 999, 3399, 1285 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 999, 3399, 1285 is 1.
Highest Common Factor of 999,3399,1285 is 1
Step 1: Since 3399 > 999, we apply the division lemma to 3399 and 999, to get
3399 = 999 x 3 + 402
Step 2: Since the reminder 999 ≠ 0, we apply division lemma to 402 and 999, to get
999 = 402 x 2 + 195
Step 3: We consider the new divisor 402 and the new remainder 195, and apply the division lemma to get
402 = 195 x 2 + 12
We consider the new divisor 195 and the new remainder 12,and apply the division lemma to get
195 = 12 x 16 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 999 and 3399 is 3
Notice that 3 = HCF(12,3) = HCF(195,12) = HCF(402,195) = HCF(999,402) = HCF(3399,999) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 1285 > 3, we apply the division lemma to 1285 and 3, to get
1285 = 3 x 428 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 1285 is 1
Notice that 1 = HCF(3,1) = HCF(1285,3) .
